Features of Spacer Amidites

• Spacer phosphoramidites are used to place spacer arms into oligonucleotides.
  C₃, C₆ and C₁₂ spacer phosphoramidites contain an aliphatic linker which can be added to oligos requiring long spacer arms. In general, spacer phosphoramidites are used during oligonucleotide synthesis to introduce a spacer into the sequence, bridging sections of an oligonucleotide.
• C₆ disulfide phosphoramidites contain a disulfide linker which can be added to oligos requiring disulfide spacer arms.
• 12, 18 atom spacer phosphoramidites contain an ethylene glycol linker which can be added to oligos requiring ethylene glycol spacer arms.
• Abasic and dSpacers are used to introduce a stable abasic site within an oligonucleotide.
• Hexadecane and octadecane phosphoramidites are hydrophobic.
